  • Phylogeny of Ensifera (Hexapoda: Orthoptera) Using Three Ribosomal Loci, with Implications for the Evolution of Acoustic Communication
    Molecular Phylogenetics and Evolution 38 (2006) 510–530 www.elsevier.com/locate/ympev Phylogeny of Ensifera (Hexapoda: Orthoptera) using three ribosomal loci, with implications for the evolution of acoustic communication M.C. Jost a,*, K.L. Shaw b a Department of Organismic and Evolutionary Biology, Harvard University, USA b Department of Biology, University of Maryland, College Park, MD, USA Received 9 May 2005; revised 27 September 2005; accepted 4 October 2005 Available online 16 November 2005 Abstract Representatives of the Orthopteran suborder Ensifera (crickets, katydids, and related insects) are well known for acoustic signals pro- duced in the contexts of courtship and mate recognition. We present a phylogenetic estimate of Ensifera for a sample of 51 taxonomically diverse exemplars, using sequences from 18S, 28S, and 16S rRNA. The results support a monophyletic Ensifera, monophyly of most ensiferan families, and the superfamily Gryllacridoidea which would include Stenopelmatidae, Anostostomatidae, Gryllacrididae, and Lezina. Schizodactylidae was recovered as the sister lineage to Grylloidea, and both Rhaphidophoridae and Tettigoniidae were found to be more closely related to Grylloidea than has been suggested by prior studies. The ambidextrously stridulating haglid Cyphoderris was found to be basal (or sister) to a clade that contains both Grylloidea and Tettigoniidae. Tree comparison tests with the concatenated molecular data found our phylogeny to be significantly better at explaining our data than three recent phylogenetic hypotheses based on morphological characters. A high degree of conflict exists between the molecular and morphological data, possibly indicating that much homoplasy is present in Ensifera, particularly in acoustic structures. In contrast to prior evolutionary hypotheses based on most parsi- monious ancestral state reconstructions, we propose that tegminal stridulation and tibial tympana are ancestral to Ensifera and were lost multiple times, especially within the Gryllidae.

  • A Comparative Study of Mating Behaviour in Some Neotropical Grasshoppers (Acridoidea)
    Ethology 76, 265-296 (1987) 0 1987 Paul Parey Scientific Publishers, Berlin and Hamburg ISSN 0179-1613 Max-Planck-Institut fur Verhaltensphysiologie, Seewiesen A Comparative Study of Mating Behaviour in Some Neotropical Grasshoppers (Acridoidea) KLAUSRIEUE With 11 figures and one colour plate Received: September 23, 1986 Accepted: January 20, 1987 (W. Wickler) Abstract Aspects of premating and mating behaviour in several South American grasshopppers (Acridoidea) are described and compared. Examples of communication by acoustical, visual and chemical means are given. Acoustic signals are emitted only by species of the subfamilies Gomphocerinae, Acridinae, Romaleinae and Copiocerinae. Each subfamily has distinct sound-producing mechanisms, and the songs occur in different behavioural contexts. In Gomphocerinae and Acridinae the sexes recognize and attract each other by species-specific songs produced by a femuro-tegminal stridulatory mecha- nism. In contrast, Romaleinae produce a simple song by rubbing the hindwings against the forewings. These songs are similar in different species and no attraction of females could be demonstrated, but the behaviour may function in male-male interaction and during copulation. Sexual pheromones also play a role in this subfamily. Acoustic activity during copulation has been observed in Aleuasini (Copiocerinae), but its function is still unclear. No sound production at all exists in the Leptysminae, Rhytidochrotinae, Ommatolampinae, Melanoplinae, Proctolabinae and Bactrophorinae, but conspicuous movements of hindlegs (knee- waving) and antennae were observed. In some species these form part of a soundless courtship display. Ecological constraints have little influence on the basic mating strategies: romaleine, gom- phocerine and melanopline grasshoppers often coexist in various habitats, but show the divergent behaviour patterns characteristic of their respective subfamilies.

  • A Review of Australian Copiphorini (Orthoptera : Tettigoniidae : Conocephalinae)
    Aust. J. Zool., 1979, 27, 1015-49 A Review of Australian Copiphorini (Orthoptera : Tettigoniidae : Conocephalinae) Winston J. Bailey Department of Zoology, University of Western Australia. Nedlands. W.A. 6009. Abstract The Australian members of the tribe Copiphorini (Tettigoniidae) are reviewed and their relationship to the Indo-Pacific species clarified. The principal character used is the stridulatory file of the male. This permits clear distinction of species within the four genera Pseudorhynchus, Euconocephalus, Ruspolia and Mygalopsis. Seven new species are named: P. raggei, P. selonis, E. broughtoni, R. marshallae, M. sandowi, M. marki and M. thielei. All genera are keyed, all species described and synonyms given. Distribution patterns are noted but not discussed in any detail. Introduction The Australian Tettigoniidae have had scant taxonomic treatment in recent times. Riek (1976) has provided a review of one genus, Tympanophora, and a number of other families are at present under consideration. Studies on the ecology, behaviour and physiology of various genera of Tettigoniidae are becoming more numerous, and the present review stems from a need to bring some taxonomic order to one genus, Mygalopsis, which is receiving considerable attention from both ecologists and physiologists in Western Australia (Sandow and Bailey 1978; Bailey and Stephen 1978; Thiele and Bailey 1980). The tribe Copiphorini was erected by Karny (1912) and includes four Australian genera: Pseudorhynchus Serville, Euconocephalus Karny, Ruspolia Schulthess (= Homorocoryphus Karny) and Mygalopsis Redtenbacher. These genera were re- viewed in part, in a study of Malayan, Melanesian and Australian tettigoniids by Hebard (1922). He pointed to the poor treatment one genus had received from previous workers, notably Euconocephalus.

Os insetos foram obtidos da criação existente no Laboratório de Entomologia, do Departamento de Biologia, da UFRPE. O material coletado foi fixado em Boüin alcoólico e processado para inclusão em "paralast". Os resultados mostraram que os órgãos do estomodeu apresentam-se constituídos por tecido epitelial simples, recoberto por uma íntima contendo espículas, exceto no proventrículo, e tecido muscular estriado envolvendo esses órgãos. No proventrículo a camada epitelial se projeta para a luz formando 12 dobras maiores intercaladas por dobras menores. Não foi evidenciada a presença de tecido conjuntivo nos órgãos do estomodeu.

This is known to promote a host of ecosystem services, and indeed agricultural landscapes that include perennials have been shown to support wildlife, enhance pest regulation, sequester carbon, limit erosion and water pollution, and promote pollination. Yet, the agroforestry and agroecology literatures that characterize environmental benefits of perennials (which mostly involve non-food producing trees and grasslands, especially in temperate climates) are largely separate from agronomic literature about the management and yields of perennial crops themselves.
